Ne4ueva [31]

In my own words, physical storage... (physical being the key word) is something that you can touch, e.g. hard drive, USB, blank DVD or CD.

Virtual storage - cloud-based storage. Files are saved/back-up on to the cloud (we don't necessarily need a USB for this), just access to the internet, e.g. Google drive, iCloud.

Which of the following rights is NOT guaranteed by copyright?

sleet_krkn [62]

Answer:

A. Right to avoid criticism

Explanation:

Patent can be defined as the exclusive or sole right granted to an inventor by a sovereign authority such as a government, which enables him or her to manufacture, use, or sell an invention for a specific period of time.

Generally, patents are used on innovation for products that are manufactured through the application of various technologies.

Basically, the three (3) main ways to protect an intellectual property is to employ the use of

I. Trademarks.

II. Patents.

III. Copyright.

Copyright law can be defined as a set of formal rules granted by a government to protect an intellectual property by giving the owner an exclusive right to use while preventing any unauthorized access, use or duplication by others.

Hence, the right that is not guaranteed by copyright laws is the right to avoid criticism because as an author or writer your literary work is subject to criticism from the readers and by extension the general public.

Open the Undergrad Debt data in the Excel file. Nationally, on average, a college student last year graduated with $27,200 in de

Rom4ik [11]

Answer:

Arkansas students have higher debt than the national average, $27,200.

Explanation:

The provided data is:

S = {24040, 19153, 26762, 31923, 31533, 34207, 14623, 24370, 31016}

In this case we need to test whether Arkansas students have higher debt than the national average at alpha equal to 0.10.

The hypothesis can be defined as follows:

H₀: Arkansas students does not have higher debt than the national average, i.e. μ ≤ $27,200.

Hₐ: Arkansas students have higher debt than the national average, i.e. μ > $27,200.

Compute the sample mean:

$\bar x=\frac{1}{n}\sum X=\frac{1}{10}\times 213537=21353.70$

As the population standard deviation is provided, we will use a z-test for single mean.

Compute the test statistic value as follows:

$z=\frac{\bar x-\mu}{\sigma/\sqrt{n}}=\frac{21353.70-27200}{5000/\sqrt{10}}=-3.70$

The test statistic value is -3.70.

Decision rule:

If the p-value of the test is less than the significance level then the null hypothesis will be rejected.

Compute the p-value for the test as follows:

$p-value=P(Z>-3.70)=P(Z$

*Use a z-table for the probability.

The p-value of the test is 0.00011.

p-value = 0.00011 < α = 0.10

The null hypothesis will be rejected.

Thus, it can be concluded that Arkansas students have higher debt than the national average, $27,200.
